Coordinate filters work only when the program prompts you for a point. If
you try to use a coordinate filter at the Command prompt, you see an error
message.
Example: Use of Coordinate Filters in 3D
This example shows how to use coordinate filters to create a point object at
the center (centroid) of a 3D object. Hidden lines have been removed for
clarity. The X value of the new point is extracted from the first location
specified, the Y value from the second location, and the Z value from the third.
The three values are combined to form the coordinate values of the new point.
Command: point
Point: .x
of mid
of select object (1)
(need YZ): .y
of mid
of select object (2)
(need Z): mid
of select object (3)
To use coordinate filters to specify a point in 2D
1 At the prompt for a point, enter a coordinate filter (.x or .y).
For example, enter .x to specify the X value first.
2 To extract the first coordinate value, specify a point.
For example, if you entered .x in step 1, the X value is extracted from this
point.
3 To extract the next coordinate value, specify a different point.
The new point location combines the coordinate values extracted from
the points you specified in steps 2 and 3.
